Abstract
The wind disturbance greatly affects to the vehicle´s behaviour provoking that the vehicle does not follow the desired trajectory. This paper presents a new yaw moment control based on fuzzy logic to improve the vehicle handling and stability in crosswind. The advantages of fuzzy methods are their simplicity and their good performance to control nonlinear systems. The developed controller generates the suitable yaw moment which is obtained from the difference of the brake forces between the front wheels so that the vehicle follows the target values of the yaw rate and the side slip angle. The simulations results show the effectiveness of the proposed control method when the vehicle is subjected to different cornering steering maneuvers, such as change lane and Jturn, and a wind disturbance.
